BancFirst's second quarter was the strongest in the company's history on almost every measure that matters, with net interest income of $133.5M (+10.1% year over year) lifting diluted earnings per share to $1.96 (GAAP, +5.9%) and the net interest margin to 3.84% (+0.09 percentage points year over year), but the load-bearing question for the equity is no longer the quarter itself - it is the credit migration that lifted nonaccrual loans to 0.94% of total loans from 0.72% at year-end 2025 and the announced $939.6M-asset SpiritBank acquisition that will add roughly 6% to the balance sheet on top of last November's $414M-asset American Bank of Oklahoma close. The market is paying 15.6x trailing earnings and roughly 2.0x book for a stock that has compounded book value per share at 12% over the past five years but has compounded earnings per share at only 4% over the same window - the load-bearing divergence is whether the SpiritBank deal restores the EPS growth that has lagged the equity story, or whether the rising nonaccrual line is the leading edge of a credit cycle the broader industry has not yet priced.
